Technology grows up, day to day to facilitate human beings’ lifestyle, in order to protect them and their properties. Cloud computing is a platform that one hardware is shared by different clients in the virtual ways and works as standalone physical hardware, is accessed everywhere at any time through the internet. Security is an essential and a vital point to all customers is belonged in the same physical component. This survey paper discusses about cloud computing challenges, types of attacks, and currently solutions in the details. Furthermore, cloud security of models as application, network, and deployment and also services. Cloud security based on a distributed ledger helps the clients to operate within transparency manners and is decentralized to enhance cloud computing information security principals, cloud security requirements, cloud security control, and security design of cloud computing

In this era of science where we want things to get more durable and affectless from outer element like corrosion, wear, water, friction, biofouling etc, in this which reduction of wettability is an important phenomenon. we try to mimic water repellence property from our nature to reduce contact with water like a lotus leaf, rose petal, cicada wings etc, this effect is known as superhydrophobicity. In this paper, we have discussed a general introduction about superhydrophobicity and will focus on its application in different fields. In this review paper, there are a lot of examples of coatings that are made by different researchers. We have discussed extensive area of application of superhydrophobicity like corrosion reduction, marine industries, aeroplane industry, self-cleaning, anti-icing, wear resistivity etc.

Maximum life span (or,  for humans, maximum reported age at death) is a measure of the maximum amount of time one or more members of a population have been observed to survive between birth and death. The term can also denote an estimate of the maximum amount of time that a member of a given species could survive between birth and death, provided circumstances that are optimal to that member's longevity. In the absence of age-specific mortality data, the estimation of age dependent parameter r(t) in this article leads us to infer that the maximum life span of women can be estimated using the scale parameter α.
